Conventional wisdom holds that simultaneous use of 802.11b in a single location without interference is limited to the three non-overlapping channels in the 2.4 GHz ISM band, which can severely complicate Wi-Fi deployment strategies. According to this article, the particulars of 802.11b actually permit simultaneous use of 4 slightly overlapping channels -- with less than 5% interference between channels. (Thanks, Nate!)
